Description

Die Erfindung betrifft eine Lüftungs- und Heizeinrichtung für Einzelräume u. dgl., bestehend aus einem mit gasförmigen oder flüssigen Brennstoffen beheizten Brenner und einem oder mehreren von Heizwasser und/oder Brauchwasser durchflossenen Wärmetauschern, wobei die Heißgase des Brenners über eine mit einem Abgasgebläse versehene Abgasleitung ins Freie geführt werden und in der Abgasleitung hinter den Wärmeaustauschern ein Frischluft-Wärmeaustauscher angeordnet ist, an den eine in den Einzelraum mündende Frischluftleitung angeschlossen ist.The invention relates to a ventilation and heating device for individual rooms and. Like., consisting of a burner heated with gaseous or liquid fuels and one or more heat exchangers through which heating water and / or process water flows, the hot gases of the burner being led outside via an exhaust pipe provided with an exhaust gas blower and into the exhaust pipe behind the heat exchangers Fresh air heat exchanger is arranged, to which a fresh air line leading into the individual room is connected.

Bei einer aus der FR-A-2 344 795 bekannten Lüftungs- und Heizeinrichtung für ein Miethaus wird zum Zwecke einer besseren Wärmeausnutzung das Heizgas der Kessel mit zusätzlicher Luft aus dem Heizungsraum mittels eines Ventilators über Rohrleitungen in den Außenfassaden zu den einzelnen Etagen geführt, wo diese Rohrleitungen jeweils in Verbindung mit der Frischluftzufuhr dienenden Rohrleitungen in der Art eines Wärmeaustauschers verbunden sind und eine Frischlufterwärmung stattfindet. Um außerhalb der Heizperiode ohne Beheizung der Etagen durch Verbrennungsluft eine allgemeine Brauchwassererwärmung zu ermöglichen, ist in der Abgasleitung zwischen den Kesseln und dem Ventilator ein von kaltem Brauchwasser durchströmter Wärmetauscher angeordnet, der das Gemisch aus Verbrennungsgas und Raumluft entsprechend abkühlt und das Brauchwasser vorwärmt. Diese bekannte Lüftungs- und Heizeinrichtung führt zwar zu einer Abkühlung der Abgase auf eine Temperatur, bei der die Etagen nicht durch Abgaswärme beheizt werden, erlaubt jedoch keine Abkühlung der Frischluft für Klimatisierungszwecke. Sowohl die boilerartigen Kessel wie auch das der Abgasleitung zugeordnete Rohrsystem lassen eine Abkühlung der Abgase bis unter ihren Taupunkt praktisch nicht zu.In a ventilation and heating device for a rental house known from FR-A-2 344 795, the heating gas of the boiler with additional air from the boiler room is led to the individual floors via pipes in the outer facades for the purpose of better heat utilization, where these pipes are each connected in connection with the fresh air supply pipes in the manner of a heat exchanger and fresh air heating takes place. In order to enable general hot water heating outside the heating period without heating the floors with combustion air, a heat exchanger through which cold hot water flows is arranged in the flue gas pipe between the boilers and the fan, which cools the mixture of combustion gas and ambient air accordingly and preheats the hot water. This known ventilation and heating device leads to a cooling of the exhaust gases to a temperature at which the floors are not heated by exhaust gas heat, but does not allow cooling of the fresh air for air conditioning purposes. Both the boiler-like boilers and the pipe system assigned to the flue pipe practically do not allow the flue gases to cool down below their dew point.

Die Erfindung befaßt sich mit der Aufgabe, eine solche Lüftungs- und Heizeinrichtung durch Verwendung der bis weit unter den Taupunkt abgekühlten Abgase für Klimatisierungszwecke nutzbar zu machen. Erreicht wird dies erfindungsgemäß dadurch, daß sämtliche Wärmetauscher aus keramischem Werkstoff bestehen, die Frischluftleitung mit einem Frischluft-Gebläse versehen ist und die Heizgase bis unter den Taupunkt abgekühlt werden.The invention is concerned with the task of making such a ventilation and heating device usable for air conditioning purposes by using the exhaust gases which have cooled far below the dew point. This is achieved according to the invention in that all heat exchangers are made of ceramic material, the fresh air line is provided with a fresh air blower and the heating gases are cooled to below the dew point.

Durch die Verwendung von Wärmetauschern aus keramischem Werkstoff zu Erwärmung von Heizwasser und/oder Brauchwasser ist eine Abkühlung der Heizgase des Brenners bis unter den Taupunkt,möglich. Das bis unter den Taupunkt abgekühlte Abgas gestattet in einfacher Weise eine Klimatisierung des Einzelraumes, indem die dem Einzelraum durch ein Frischluft-Gebläse zugeführte Frischluft an heißen Tagen abgekühlt und an kalten Tagen aufgeheizt wird. Bei der Erwärmung kälterer Frischluft durch die vom Abgas abgegebene Wärme wird einerseits zusätzlich die im Abgas freigesetzte Kondensationswärme nutzbar gemacht, und andererseits wird gegenüber dem Abgas wärmere Frischluft abgekühlt, wobei die vom Abgas aufgenommene Wärme der Frischluft entzogen wird. Außerdem wird durch die erfindungsgemäß vorgesehene Werkstoffwahl (Keramik) verhindert, daß die aggressiven, nassen Abgase die Wärmetauscher zerstören.By using heat exchangers made of ceramic material to heat the heating water and / or process water, the heating gases of the burner can be cooled down to below the dew point. The exhaust gas cooled down to below the dew point allows air conditioning of the individual room in a simple manner by cooling the fresh air supplied to the individual room by a fresh air blower on hot days and heating it up on cold days. When colder fresh air is heated by the heat emitted by the exhaust gas, on the one hand the condensation heat released in the exhaust gas is made usable, and on the other hand warmer fresh air is cooled compared to the exhaust gas, the heat absorbed by the exhaust gas being extracted from the fresh air. In addition, the choice of materials (ceramics) according to the invention prevents the aggressive, wet exhaust gases from destroying the heat exchangers.

Die Zufuhr von Frischluft kann auf einfache Art und Weise durch eine in der Frischluftleitung vor dem Frischluft-Gebläse angeordnete Drosselklappe gesteuert oder geregelt werden. Weiterhin besteht die Möglichkeit, die Frischluftleitung im Bereich zwischen der Drosselklappe und dem Frischluft-Gebläse mit einer oder mehreren Bypass-Öffnungen zu versehen, durch welche Raumluft angesaugt und mit der abgekühlten Frischluft vermischt wird; hierdurch wird vermieden, daß stark unterkühlte Frischluft an einer Stelle in den Raum einströmt.The supply of fresh air can be controlled or regulated in a simple manner by means of a throttle valve arranged in the fresh air line in front of the fresh air blower. It is also possible to provide the fresh air line in the area between the throttle valve and the fresh air blower with one or more bypass openings through which room air is drawn in and mixed with the cooled fresh air; this prevents strongly supercooled fresh air from flowing into the room at one point.

Die Raumluft befindet sich ständig im Austausch, indem die Heizeinrichtung dem Einzelraum ständig Verbrennungsluft entnimmt und klimatisierte Frischluft eingeführt wird. Die Abführung von Raumluft läßt sich dadurch verstärken, daß die Abgasleitung zwischen den Wärmeaustauschern und dem Abgas-Gebläse mit einer Bypass-Öffnung versehen ist.The room air is constantly exchanged by the heating device constantly taking combustion air from the individual room and introducing conditioned fresh air. The removal of room air can be increased by providing the exhaust line between the heat exchangers and the exhaust fan with a bypass opening.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Einem Einzelraum 1 o. dgl. ist eine Heizeinrichtung 2 zugeordnet, die im wesentlichen aus einer Brenner- und Brennkammereinheit 3 und zwei Wärmeaustauschern 4, 5 besteht, von denen der erste vom Heizwasser einer Heizwasseranlage und der zweite von Brauchwasser durchflossen wird. Der Brenner wird mit gasförmigem'oder flüssigem Brennstoff beheizt, und das in der Brennkammer gebildete Heißgas tritt in den ersten Wärmeaustauscher 4 mit einer Temperatur von über 1000°C ein und durchströmt diesen sowie den Wärmeaustauscher 5. Durch die beiden Wärmeaustauscher 4, 5 wird das Heißgas bis unter den Taupunkt abgekühlt. Das im Wärmeaustauscher 5 abgeschiedene Kondensatwasser wird über eine nicht dargestellte Ableitung abgeführt. Die keramischen Wärmeaustauscher 4, 5 weisen eine Vielzahl parallel liegender, schlitzförmiger Strömungskanäle auf, die von dem Heißgas sowie von dem zu erwärmenden Heizwasser bzw. Brauchwasser durchströmt werden. Das von den Wärmeaustauschern bis unter den Taupunkt abgekühlte Heißgas wird mittels einer durch eine Außenwand 7 geführte und mit einem Abgas-Gebläse 8 versehene Abgasleitung 6 ins Freie geführt.A heating device 2 is assigned to a single room 1 or the like, which essentially consists of a burner and combustion chamber unit 3 and two heat exchangers 4, 5, the first of which is flowed through by heating water from a heating water system and the second by process water. The burner is heated with gaseous or liquid fuel, and the hot gas formed in the combustion chamber enters the first heat exchanger 4 at a temperature of over 1000 ° C. and flows through it and through the heat exchanger 5. This becomes through the two heat exchangers 4, 5 Hot gas cooled to below the dew point. The condensate water separated in the heat exchanger 5 is discharged via a drain, not shown. The ceramic heat exchangers 4, 5 have a plurality of parallel, slit-shaped flow channels through which the hot gas and the heating water or process water to be heated flow. The hot gas cooled by the heat exchangers to below the dew point is led outside by means of an exhaust line 6 which is led through an outer wall 7 and provided with an exhaust gas blower 8.

In der Abgasleitung 6 ist ein keramischer Frischluft-Wärmeaustauscher 9 angeordnet, der ähnlich wie die Wärmeaustauscher 4, 5 aufgebaut ist und einerseits von dem unter den Taupunkt abgekühlten Abgas und andererseits von Frischluft durchströmt wird. Auf der Raumseite befindet sich eine Frischluftleitung 10, durch welche die Frischluft mittels eines Frischluft-Gebläses 11 aus dem Freien angesaugt wird und dabei den Frischluft-Wärmeaustauscher 9 durchströmt. In der Frischluftleitung 10 ist weiterhin eine Drosselklappe 12 angeordnet, mit deren Hilfe die Frischluftmenge einstellbar ist. Außerdem sind zwischen der Drosselklappe 12 und dem Frischluft-Gebläse 11 in der Frischluftleitung 10 ein oder mehrere Bypass-Öffnungen 13 vorgesehen, durch welche Luft aus dem Einzelraum 1 angesaugt wird. Ähnliche Bypass-Öffnungen 14 können auch zwischen dem Wärmeaustauscher 5 und dem Abgas-Gebläse 8 in der Abgasleitung 6 angeordnet sein.A ceramic fresh air heat exchanger 9 is arranged in the exhaust line 6, which is constructed similarly to the heat exchangers 4, 5 and on the one hand from the exhaust gas cooled below the dew point and on the other hand from Fresh air is flowing through. On the room side there is a fresh air line 10, through which the fresh air is sucked in from the outside by means of a fresh air blower 11 and thereby flows through the fresh air heat exchanger 9. A throttle valve 12 is also arranged in the fresh air line 10, with the aid of which the amount of fresh air can be adjusted. In addition, one or more bypass openings 13 are provided between the throttle valve 12 and the fresh air blower 11 in the fresh air line 10, through which air is sucked in from the individual space 1. Similar bypass openings 14 can also be arranged between the heat exchanger 5 and the exhaust gas blower 8 in the exhaust line 6.

Bei Betrieb der Heizeinrichtung 2 wird dem Einzelraum 1 Raumluft als Verbrennungsluft entnommen. Nach Verlassen der Wärmeaustauscher 4, 5 und nach Beimischen von Raumluft an der bzw. den Bypass-Öffnungen 14 wird das weit unter den Taupunkt abgekühlte Abgas vom Abgas-Gebläse 8 über die Abgasleitung 6 durch den Frischluft-Wärmeaustauscher 9 und das außen liegende Abgasrohr 6 in das Freie geleitet. Frischluft wird im Gegenstrom durch den Frischluft-Wärmeaustauscher 9 mittels Frischluft-Gebläses 11 in den Einzelraum 1 geleitet. Dabei kann an einem heißen Tag mit Außentemperaturen, die um fünf oder mehr Celsiusgrade höher liegen als die Abgastemperatur, in der Abgasleitung 6 die Frischluft um drei bis fünf oder mehr Celsiusgrade abgekühlt in den Einzelraum 1 gegeben werden. Durch Zumischung von Raumluft über die Bypass-Öffnungen 13 wird vermieden, daß die vom Frischluft-Gebläse 11 in den Einzelraum 1 geförderte Luft zu stark unterkühlt an einer Stelle einströmt. An einem kalten Tag, bei dem die Außentemperatur niedriger als im Einzelraum 1 ist, ist die Temperatur in der Abgasleitung 6 und fünf oder mehr Celsiusgrade wärmer, so daß die aus dem Freien eintretende Frischluft im Frischluft-Wärmeaustauscher um vier oder mehr Celsiusgrade aufgewärmt werden wird.When the heating device 2 is operating, room air is extracted from the individual room 1 as combustion air. After leaving the heat exchangers 4, 5 and after admixing room air at the bypass openings 14, the exhaust gas cooled far below the dew point is exhausted by the exhaust gas fan 8 via the exhaust line 6 through the fresh air heat exchanger 9 and the external exhaust pipe 6 led into the open. Fresh air is conducted in counterflow through the fresh air heat exchanger 9 by means of fresh air blower 11 into the individual room 1. In this way, on a hot day with outside temperatures that are five or more degrees Celsius higher than the exhaust gas temperature, the fresh air can be introduced into the individual space 1 in the exhaust line 6, cooled by three to five or more degrees Celsius. By admixing room air via the bypass openings 13, it is avoided that the air conveyed into the individual room 1 by the fresh air blower 11 flows in excessively supercooled at one point. On a cold day, when the outside temperature is lower than in the individual room 1, the temperature in the exhaust gas line 6 and five or more degrees Celsius is warmer, so that the fresh air entering from outside will be warmed up in the fresh air heat exchanger by four or more degrees Celsius .

Es hat sich gezeigt, daß bei einer Heizeinrichtung der genannten Art, die beispielsweise zum Beheizen einer kleinen Wohnung benutzt wird und die dort in einem sogenannten Küchenzentrum untergebracht sein kann, die austretende Abgasmenge aus der Heizeinrichtung ausreichend groß ist, um in der Küche gleichzeitig die ständige Lufterneuerung für die in der Küche arbeitenden Personen und auch die Klimatisierung herbeizuführen, ähnlich wie ein dafür bisher separat benutztes Raumklimagerät. Mit der erfindungsgemäßen Heizeinrichtung für Frischluftklimatisierung durch Abgase kann der für die Klimatisierung benötigte Aufwand im Vergleich zu einem äquivalenten Klimagerät deutlich geringer gehalten werden, und es entsteht auch ein kleinerer Raumbedarf als bei den separaten Raumklimageräten. Über die Drosselklappe 12 in der Frischluftleitung 10 vor dem Frischluft-Gebläse 11 kann die in den Einzelraum 1 eingegebene Menge zwischen einem Höchstwert bei geöffneter Drosselklappe und bei minimalem Wert bei geschlossener Drosselklappe auf die jeweiligen atmosphärischen Temperaturverhältnisse bezüglich der konstant zu haltenden Temperatur im Einzelraum 1 eingestellt werden. Durch die Verwendung von keramischem Werkstoff für den Frischluft-Wärmeaustauscher 9 wird insbesondere bei Frischlufterwärmung an kalten Tagen erreicht, daß die Frischluft-Wärmeaustauscher 9 stattfindende Kondensation von Abgas-Verbrennungswasserdampf, insbesondere bei Verbrennung schwefelhaltiger Brennstoffe keine materialschädigende Auswirkung hat. Der für den Antrieb des Frischluft-Gebläses 11 erforderliche Strombedarf liegt um etwa 1/5 bis 1/10 niedriger als die für die Frischluftklimatisierung an die Frischluft übertragene oder von der Frischluft entnommene Wärmeleistung. Von besonderem Vorteil ist es, wenn die Heizeinrichtung kontinuierlich, d. h. ständig betrieben wird; dann wird eine ebenso kontinuierliche Raumklimatisierung erreicht. Bei Betriebssituationen, bei denen die Heizeinrichtung 2 abgeschaltet ist, kann mit der erfindungsgemäßen Einrichtung auch bei nur eingeschaltetem Frischluft-Gebläse 11 und/oder Abgas-Gebläse 8 der Einzelraum 1 ständig belüftet werden.It has been shown that in a heating device of the type mentioned, which is used, for example, for heating a small apartment and which can be accommodated there in a so-called kitchen center, the amount of exhaust gas escaping from the heating device is sufficiently large to ensure that the kitchen is constantly at the same time To bring about air renewal for the people working in the kitchen and also the air conditioning, similar to a previously used room air conditioner. With the heating device according to the invention for fresh air conditioning by exhaust gases, the effort required for air conditioning can be kept significantly lower in comparison to an equivalent air conditioning device, and there is also a smaller space requirement than with the separate room air conditioning devices. Via the throttle valve 12 in the fresh air line 10 in front of the fresh air blower 11, the quantity entered into the individual room 1 can be adjusted between the maximum value when the throttle valve is open and the minimum value when the throttle valve is closed to the respective atmospheric temperature conditions with regard to the temperature to be kept constant in the individual room 1 will. Through the use of ceramic material for the fresh air heat exchanger 9, in particular with fresh air heating on cold days, it is achieved that the fresh air heat exchanger 9 condensation of exhaust gas combustion water vapor, in particular when burning sulfur-containing fuels, has no material-damaging effect. The required for driving the fresh air blower 11 power requirement is about 1/5 bis tenth lower than the transmitted or for the fresh air conditioning to the fresh air drawn by the fresh air heat output. It is particularly advantageous if the heating device is operated continuously, ie continuously; then an equally continuous air conditioning is achieved. In operating situations in which the heating device 2 is switched off, the individual room 1 can be constantly ventilated with the device according to the invention even when the fresh air blower 11 and / or exhaust gas blower 8 is only switched on.

Unangenehme Küchendünste werden sowohl bei eingeschalteter oder abgeschalteter Heizungsanlage durch die Heizeinrichtung 2 am Eintritt 15 der Heizeinrichtung angesaugt, wenn dies im zu klimatisierenden Einzelraum 1, beispielsweise in einem Beistellschrank, neben dem Kochherd betrieben wird. Eine Dunstabzugshaube ist dann nicht mehr nötig.Unpleasant kitchen vapors are sucked in by the heating device 2 at the inlet 15 of the heating device both when the heating system is switched on or off when this is operated in the individual room 1 to be air-conditioned, for example in a side cabinet next to the cooker. An extractor hood is then no longer necessary.
